PROVIDENCE, R.I. - Richard Hatch has been sent to a federal prison in Oklahoma as he serves a 51-month sentence for failing to pay taxes on the $1 million he won on the debut season of "Survivor."

Hatch, 45, of Newport, arrived last week at the Federal Transfer Center in Oklahoma City. It wasn't immediately clear why Hatch was moved or whether he will serve out his prison sentence at the facility, which is a hub for prisoners transferring through the federal system.
